July 6, 2012 // 1:11 am - Following up on my PSN / SEN Enabler & Disabler 4.20 release, I have now upgraded them to version 4.21 and included ReActPSN compatibility support, which is not mandatory for log in SEN.

It also includes a GUI for enabling PSN / SEN so if something is wrong it will restore your PS3 files preventing a RSOD on the PlayStation 3 console.

ALLOW SEN ACCESS - INSTALL ONLY PKG FOR YOUR CFW

SEN Enabler & Disabler [4.21]

This enable (4.21) or disable SEN access for your CFW, simply install *ONLY THE PKG FOR YOUR CFW* (CFW Kmeaw = PKG for Kmeaw) and run it in XMB, you will see the menu, first if you wish to continue choose "Yes" or if you wish exit to XMB choose "No".

If you continue program will ask you if you want enable fix, and for disable in this screen choose "No" and you will be able to disable fix. At the moment of enabling fix, it will create a backup of your dev_flash files to restore and prevent RSOD

hi, i'm running a phat ps3, cechlo1 with the latest OFW. and i have RSoD. i was wondering what i can do to fix this, nothing seems to work. if it'll help any i have a ti 84 plus. but the only thing i can do is get to the recover menu/safe mode if those are the same things.

Following up on his PSN / SEN Enabler and Disabler v4.31, PlayStation 3 homebrew developer Nathan_r32_69 (aka nathanr3269) has released a PS3 PUP's Syscon Changer v1.0 followed by v1.1, v1.2 and v2.0 for those interested with details below.

To quote: Hi friends, i'm here again with a new tool to make it easy another task, this time to change PUP's syscon, for for example, install a lower PUP on higher firmware, like Downgrader PUPs does

USE IT WITH CAUTION - ONLY FOR CFW FOR NOW

Its to easy to use, only chose your PUP file, select syscon version and click on "Start", if all goes fine you will have a new file named "NEW-PS3UPDAT.PUP"

Hope you will find this tool useful and contact me if you see any issue, meanwhile i'll back to finish SEN Enabler v5.0 and other research

Finally, from Cyberskunk: Basically this changes the firmware version in the info0 of the CORE_OS_PACKAGE.pkg so the PS3 thinks you are installing a higher CoreOS.. Same way the '999' Downgrader works.. And NO.. It will never downgrade 3.56+ OFW.. Ever!!

To do do this you would need to exploit the OFW and try to stop it from checking the spkg_hdr.1 files or return success (if you had an exploit like this you could do a hell of a lot more than just installing firmware)

OR Some disgruntled employee at Sony would need to leak the private key for spkg_hdr.1 files. This private key can no longer be calc'd and it is not, never has been nor will ever be in the firmware. Sorry to burst any bubbles of people thinking it will happen sometime soon..

v1.1 Changelog:

New version v1.1 released: PUP file must be where you unpack the program

Fixed some issues while unpackin Core_OS and creating spkg files, must work fine now

v1.2 Changelog:

Improved code

Fixed all previous bugs

Added executable to install the variable of the keys

v2.0 Changelog:

Updated code

Updated tools

Fixed some bugs

Added option to change PUP's Image version

About:

PS3's PUP Syscon Changer [aka PPSC] was developed long time ago from a request because someone was stuck on Recovery and was unable to install any CFW, with this he could fix it and then was released to everybody.

This tool changes PUP Syscon value to a higher-lower one (higher recommended), you can choose it, and then install it from Recovery Menu. A quick example of this tool is that you can install CFW 3.55 PUP on CFW 4.XX after patching it, other example is for make a DOWNGRADER PUP.

Instructions:

Is simple, follow this steps:

Select PUP on Open button (...)

Select Syscon value (From 0.00 to 9.99)

Select Image version (From 00000 to 99999) (if you want to use Image version from PUP, don't change this)

Press Start

Wait until is finished

If all goes fine you will have a file named NEW-PS3UPDAT.PUP, rename it to PS3UPDAT.PUP and copy it to a USB device and install on PS3 from Recovery Menu.

Remember, this is ONLY FOR CFW AND NOT FOR OFW, this can't make install CFW on OFW 3.56+
